Abstract
The utility model provides a polyester fibre coating filtering felt with good heat stability, good chemical gas corrosion resistance and higher filtering precision. The structure of the felt is as follows: a layer of teflon B is coated on the surface of a windward side of a polyester fibre punched felt by a foaming machine; and the polyester fibre punched felt is formed in such a way that the upper surface and the lower surface of a polyester basic cloth are symmetrically adhered to the polyester fibre layers by a needle machine in punching. The polyester fibre coating filtering felt has the advantages that the filtering felt has good chemical gas corrosion resistance, high tensile strength and good dust removal performance by using superficial filtering, is easy for cleaning dust, has high dust-cleaning resistance, ensures the filtering materials to have long service life and also realizes high filtering precision.
Description
Technical field
The utility model relates to a kind of polyster fibre coating filter felt, the filter felt that particularly a kind of filtering material that is used for flue gas and treating flour dust is made.
Background technology
At present, in the lower occasion of some filtrating smoke dust temperature, filtering material as uses such as iron-smelter, garbage burning factory, blast furnace gas length, its particle is relatively more severe to the wearing and tearing of filtrate, its coated filter material is under the effect of particle, its microporous barrier seriously reduces the precision and the service life of filtering material easily by scratch.
The utility model content
Be to solve foregoing problems, the utility model provides a kind of Heat stability is good, the chemically-resistant gas attack is good, filtering accuracy is higher polyster fibre coating filter felt; The structure of this felt is on fibrolaminar surface, the windward side of polyster fibre Nomex, to be coated with last layer Teflon B in the windward side of polyster fibre Nomex with foaming machine;
Described polyster fibre Nomex is the upper and lower surface at the terylene base cloth, is pasted with the polyster fibre layer through needing machine acupuncture symmetry.
Superior effect of the present utility model is:
(1) the chemically-resistant gas attack is good, the hot strength height;
(2) adopt surface filtration, the stripping performance of dust is good, easy-to-clean ash;
(3) anti-deashing ability height, the long service life of filtrate;
(4) filtering accuracy height.
